REINHOLD E. HENNINGES, OF CLEVELAND, OHIO.

WINDOW-SASH FASTENER.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed December 4. 1907- Serial No. 405031.

To all whom it may concern:

Be it known that I, REINHOLD E. HEN- NINGES, a citizen of the UnitedStates, and a resident of Cleveland, in the county of Guyahoga and Stateof Ohio, have invented a certain new and useful Window-Sash Fastener, ofwhich the following is a specification.

This invention relates to window sash fasteners.

The object of the invention is to roduce a sash fastener which willpermit a slight raising of the lower sash, or lowering of the up persash, but will prevent a complete opening from outside the window.

The invention consists of the construction and combination of elementshereinafter described and claimed.

Figure 1 is a broken perspective view of.the meeting rails of twosashes, with the improved fastener a plied. Fig. 2 is a section of themeeting rai s of two sashes, with fastener applied, and Fig. 3 is asectional view of a modified form of fastener.

Let A indicate the top rail of the lower sash of a window, and B thebottom rail of the upper sash. These may be of any'usual construction.

To the rail B inside the glass, I attach the anchor or plate G by screwsor other holding devices. A ring D is connected to this anchor plate G.

A short chain E is connected to ring D, so thatthe chain cannot beremoved without breakage, or the absolute detachment of parts. The chaincannot be removed by any common tool which may be passed through thespace between glasses when the window is slightly raised.

To the lower rail A, I attach an arch plate H, by any suitable means.Plate H is usually a metal casting, integral with the arch I, which archI may be of ornamental form.

At the inside of the upper part of arch I there is a hook K, over whichhook any link of chain E may be hung. The hook K may have a knob or barbL at its end, and as said hook is behind the body of the arch, when anattempt is made to reach it through the window crack, it is practicallyimpossible to detach the chain from the hook in this manner, while itmay readily be detached from inside the window. The chain links willonly pass over barb L when in proper position.

The chain should be as long as the desired latitude of movement of thesashes, say a few inches. As any link of the chain may be applied to thehook, the limit of movement of the sashes may be much less than thelength of the chain.

When it is desired to fully open the window, the chain E may be detachedfrom hook K, when the sashes will be free to move.

In Fig. 3 the outer sash carries a bracket or arch W which may besimilar to arch I or a little lower. The chain is secured at one end toeyelet D on cross-bar X of the bracket. On each end, the bracket carriesa prong Y designed to keep the chain from slipping off the ends of thecross-bar when slack. The bracket I on the inner sash is provided with ascrew M. After the proper link of the chain has been put over the hookthe screw is set up as shown in the figure. This forms a positivefastening for the chain. The screw is inaccessible by any ordinary meanswithout breaking the glass of the outer sash. When this screw fasteningis used it is impossible to remove the chain by the use of a stick orother tool passed between the meeting bars of the sashes.

I claim:

1. The combination, with the meeting rails of a pair of sashes, of achain secured to one sash, and an arch provided with a hook, and securedto the rail of the other sash, so that a link of the chain may beattached to said hook.

2. A window sash fastener consisting of an anchor ring attachable to onesash, a chain attached to said ring, and an arched piece attachable tothe other sash, and having a hook to which one of the chain links may beattached.

3. A window sash fastener consisting of a chain and anchor attachable toone of the sashes, 'a hook attachable to the other sash, and meanscooperating with the hook to retain the chain thereon.

4. A window sash fastener comprising a chain and anchor attached to onesash, a hook attached to the other sash and on which a link of the chainmay be placed and a screw serving to close the hook over the chain linkand inaccessible for removal after the parts are in operative position.
